Adulteration of rice husk in rice bran and de-oiled rice bran which are fed to various Livestock and Poultry can be identified with the aid of foldscope due to its characteristic image under foldscope

Ground rice husk: #Indiafoldscopephase 1

Various oilseed meals (the residue remains after oil extraction) are fed to Livestock and Poultry as a Protein Source/Supplement. Among feed ingredients used for feeding of animals, oilseed meals are costly. Because of this, adulteration with cheap nitrogen sources mainly urea is often problem in oilseed meals. However, simple and sensitive spot test is not available to detect urea adulteration. In this context, a simple foldscope based methodology have been developed in our lab.


 Rice bran and de-oiled bran are fed to Livestock and Poultry as energy sources. Rice husk which do not have any nutritive value is often adulterated with brans thereby reducing the quality. Currently, rice husk adulteration is identified through laborious chemical analysis. As rice husk and brans show distinctly different morphological features under foldscope, we could able to identify the adulteration of rice husk in brans.


 With this background, we visited traditional and modern dairy farms around Hyderabad and demosntrated these two methodologies to the livestock farmers/technical personnel associated with quality control of feeds with the aid of foldscope. We found most of the cottonseed meals fed to animals are often adulterated with urea and collected suspected samples for further lab analysis.

 Calcite powder and Di-calcium phosphate are macroscopically white in colour and can not be differentiated without Chemical Test. The cost of calcite is Rs.2/kg while the Cost of Di-calcium phsophate is about Rs.45/kg. Because of this, livestock farmers are often prone for cheating i.e bag may be labelled as Dicalcium Phosphate, but packed with calcite powder or Dicalcium phosphate may adulterated with calcite,
